(CNN) -- The trial of a New York television executive accused of beheading his wife starts Tuesday.

Authorities learned about the incident in February 2009 when Muzzammil Hassan went to a police station in the Buffalo, New York, suburb of Orchard Park and told officers his wife was dead, police have said.

Hassan, who founded a TV network aimed at countering Muslim stereotypes, took officers to the network's office where officers found the decapitated body of his wife, Aasiya Hassan.

Hassan has pleaded not guilty to the charge of second-degree murder in the case.

Opening arguments in the case are scheduled for Tuesday morning, CNN affiliate WIVB reported. The trial has been delayed many times, and Hassan has fired three defense attorneys before finding a suitable one, the affiliate reported.

Hassan was the chief executive officer, and Aasiya Hassan was the general manager of the network.
